The bottom metal ring is coming out & left airpod is not charging

Hello everyone. I have airpods 2nd gen &'ve been using them for 2 years. I attempted to clean the lower section of my AirPods yesterday & during the process, the metal ring on the left AirPod became detached.

Here's what it looks like. It was working but I've realised that I cannot charge my left airpod anymore. Is there any way to fix this
